I was excited about the "strike" feature for opening poop bags but find it only works sporadically and I have to rub it vigorously in order for it to work. I also am not a fan of where it attaches on the handle of the leash. When you put your hand all the way through the handle of the leash and grip the leash, the bag is right there preventing you from holding on. My solution is to attach the bag with a carbineer to the handle of the leash. It swings around but not a big deal since I already have his treat bag attached this way. It stores the poop bag rolls well and I like the loop to hold a used bag until we get to a trash can
